5.From horizon- images and snapshots, browse the windows7 image from /var/lib/libvirt/images/windows7.img and image format i tried converting this image with raw,qcow2 and iso and uploaded.

6.After uploading the image to glance When I tried to launch windows,it is boots to a screen showing launch startup repair (recommeneded) . What could be the problem if windows os is not showing up on startup repair??

Is this an issue with packstack intallation of openstack??

But it is working perfectly with virt-manager, What extra i should add to launch an instance in openstack.
